The coach of the world's fastest man says he has no problem with sprinters Dwain Chambers and Justin Gatlin competing in the London Olympics after serving doping bans.
Gatlin, the 2004 Olympic 100 metres champion and 2005 double world sprint champion, served a four-year doping ban before returning to athletics in 2010.
Gatlin is eligible under U.S. rules to compete in London if he finishes in the top three at the U.S. trials in June.
The coach of Jamaican triple Olympic gold medallist Usain Bolt, Glen Mills, says it's clear cut in regard to doping
Mills says Gatlin just has to serve his time, and he doesn't believe in life sentences.
But the picture is not so clear for former world indoor champion Chambers, who has served a two-year ban.
The Court of Arbitration for Sport will decide next week whether to uphold the British Olympic Association ban from future Games for any athlete who has committed a doping offence.
